Below the disk a hub flange jadaptedto. underlie saidfwall and the ring a y I k is secured to I the shaft e, whichfhub' isfprovided with a 7 pair of arms or bracketsextending radially therefrom at diametrically opposite points,

and in each of said brackets isv mounted on I each of which carries a counterweight, while th 0t11e1-a1-m is of curved cam formation lurality of rollers 71 adapted to contact wi l the diskjd. a

belt, chain or any other la -pivot fa belhcrank lever,- one arm 6 of i 0 and When the same hasacquired a high Ve body the counterwelghts carried on thele- Iver arms 6 Will be swung outward by cen I trifugal force, thus carrying the farms '6 nearly toahor1zontal posit on, as shown in dotted lines in Fig. 1, While the .arms gare carried into substantiallyfvertical position so thattheir rollers have raised the disk' d into engagement with the lower edge ofthe wall d, thereby tightly closing the bottom of the basketflVith the shaft continuing. to

rotate at sufficient speed to maintain the" disk in this position, the material to be dried is charged into the basket through its fun nelshaped upper end. This speed of rotation is maintained until all the liquid has been ejected by centrifugal force through the perforated wall a, which liquid will be thrown against the inner wall of the casing member y and will L ass down said wall to the bottom thereof, whereupon it will be deflected by the flange 21 and caused to pass out through the ports j at the outer ends of which it may be collected in any suitable manner. As soon as the material is sufficiently dried, the speed of rotation of the shaft 0 is reduced sufficiently to permit the counterweighted arms c to fall back to their vertical position, thus permitting the disk (Z to drop away from the basket wall a and leaving circumferential opening between the basket and disc through which the dried material will be ejected by centrifugal force, said material falling within the lower casing of, from whence it may be removed in any conwnient manner. After the basket has been emptied, the speed of rotation of the shaft is increased so as to again carry the disk into engagement with the basket in order to permit refilling of the same.

From the foregoing it will be seen that I have provided an apparatus which is comparatively simple in construction and extremely economical in operation, since all that is necessary is to regulate the speed of rotation of the shaft 0 in order to permit the charging and discharging of the material without stopping the machine.

While I have described in detail the device herein illustrated, it is to be understood that I do not thereby limit my invention to the precise features of construction shown, as I am aware that many mechanical changes and modifications may be made therein without departing from the spirit and scope of the claim hereto appended.

Having thus described my invention, what 1 claim is:

A centrifugal drying machine, comprising, in combination, a rotatable shaft, a bas ket secured to said shaft for rotation therewith and having a bottom slidable on said shaft, a pair of bell-crank levers carried by said shaft, one arm of each of said levers forming a cam member supporting said bottom and the other arm having a counterweight adapted to swing the lever on its pivot thereby to cause said bottom to slide into and out of contact with said basket, the action of said counterweights being controlled by the speed of rotation of the shaft.

In witness whereof I have signed this specification in the presence of two witnesses.
